# GRESB Data Coverages

> How Abisko determines which data coverage values to report for each GRESB year.

## Energy & Water Data Coverages

Energy data coverages can be concurrently tracked for both the **Whole Building** and across all **Spaces**. The values reported to GRESB depend on the **Reporting Level.**

* If **Reporting Level = Whole Building (Any)** → Whole Building data coverages are reported
* If **Reporting Level = Split (Landlord/Tenant)** → Spaces data coverages are reported

<Note>
  Water data coverages are tracked and reported the same way as energy data coverages.
</Note>

## GHG Data Coverages

GRESB GHG data coverage calculations for Scope 1,2,3 emissions depend on the Energy Reporting Level of each property and can be complex due to differing floor area values across energy coverages. The following examples demonstrate how Floor Area Covered and Max Floor Area values are calculated for the Asset Level Spreadsheet.

### **Reporting Level = Whole Building (Landlord Controlled)**

**Example whole building data coverages by utility type:**

| Utility Type               | Floor Area Covered    | Max Area Covered      | Data Coverage |
| :------------------------- | :-------------------- | :-------------------- | :------------ |
| Electricity                | 20,000 ft<sup>2</sup> | 20,000 ft<sup>2</sup> | 100%          |
| Fuel                       | 10,000 ft<sup>2</sup> | 15,000 ft<sup>2</sup> | 66.67%        |
| District Heating & Cooling | 10,000 ft<sup>2</sup> | 18,000 ft<sup>2</sup> | 55.55%        |
| **TOTAL ENERGY**           | 40,000 ft<sup>2</sup> | 53,000 ft<sup>2</sup> | 75.47%        |

**Scope 1 Data Coverage**

* Max Area Covered = FUEL Max Area Covered
* Floor Area Covered = FUEL Floor Area Covered

**Scope 2 Data Coverage**

* Max Floor Area = MAXIMUM (ELEC Max Area, DHC Max Area)
  * MAXIMUM (20000, 18000) = 20,000 ft<sup>2</sup>
* Energy Coverage % = SUM (ELEC Floor Area, DHC Floor Area) / SUM (ELEC Max Area, DHC Max Area)
  * SUM (20000, 10000) / SUM (20000, 18000) = 78.9%
* Floor Area Covered = Max Floor Area \* Energy Coverage %
  * 20,000 ft<sup>2</sup> \* 78.9% = 15,789 ft<sup>2</sup>

**Scope 3 Data Coverage**

* N/A (All emissions are from landlord controlled meters)

### **Reporting Level = Whole Building (Tenant Controlled)**

**Example whole building data coverages by utility type:**

| Utility Type               | Floor Area Covered    | Max Area Covered      | Data Coverage |
| :------------------------- | :-------------------- | :-------------------- | :------------ |
| Electricity                | 20,000 ft<sup>2</sup> | 20,000 ft<sup>2</sup> | 100%          |
| Fuel                       | 10,000 ft<sup>2</sup> | 15,000 ft<sup>2</sup> | 66.67%        |
| District Heating & Cooling | 10,000 ft<sup>2</sup> | 18,000 ft<sup>2</sup> | 55.55%        |
| **TOTAL ENERGY**           | 40,000 ft<sup>2</sup> | 53,000 ft<sup>2</sup> | 75.47%        |

**Scope 1 Data Coverage**

* N/A (All emissions are from tenant controlled meters)

**Scope 2 Data Coverage**

* N/A (All emissions are from tenant controlled meters)

**Scope 3 Data Coverage**

* Max Floor Area = MAXIMUM (ELEC Max Area, FUEL Max Area, DHC Max Area)
  * MAXIMUM (20000, 15000, 18000) = 20,000 ft<sup>2</sup>
* Energy Coverage % = SUM (ELEC Floor Area, FUEL Floor Area, DHC Floor Area) / SUM (ELEC Max Area, Fuel Max Area, DHC Max Area)
  * SUM (20000, 10000, 10000) / SUM (20000, 15000, 18000) = 75.47%
* Floor Area Covered = Max Floor Area \* Energy Coverage %
  * 20,000 ft<sup>2</sup> \* 75.47% = 15,094 ft<sup>2</sup>

### **Reporting Level = Split (Landlord / Tenant)**

**Scope 1 Data Coverage**

* Max Floor Area = MAXIMUM (BBCA Fuel Max Area, BBSS Fuel Max Area, TSLC Fuel Max Area)
  * MAXIMUM (4000, 10000, 16000) = 16,000 ft<sup>2</sup>
* Energy Coverage % = SUM (BBCA Fuel Floor Area, BBSS Fuel Floor Area, TSLC Floor Area)  / SUM (BBCA Fuel Max Area, BBSS Fuel Max Area, TSLC Fuel Max Area)
  * SUM (3000, 9000, 15000) / SUM (4000, 10000, 16000) = 90%
* Floor Area Covered = Max Floor Area \* Energy Coverage %
  * 16,000 ft<sup>2</sup> \* 90% = 14,400 ft<sup>2</sup>

**Scope 2 Data Coverage**

* Floor Area Covered = Max Floor Area \* Energy Coverage %
  * 18,000 ft<sup>2</sup> \* 90% = 16,200 ft<sup>2</sup>

**Scope 3 Data Coverage**

* Max Floor Area = MAXIMUM (TSTC ELEC Max Area, TSTC FUEL Max Area, TSTC DHC Max Area)
  * MAXIMUM (20000, 22000, 24000) = 24,000 ft<sup>2</sup>
